Quality Control

Our 3,18-Diethyl-1,4,5,15,16,19,22,24-Octahydro-2,7,13,17-Tetramethyl-1,19-Dioxo-21H-Biline-8,12-Dipropionic Acid is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing, including HPLC, NMR, and mass spectrometry, to ensure identity, purity, and consistency. Certificates of Analysis (COA) detailing all specifications are provided and can be tailored to meet specific customer or regulatory requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed in a dry environment to prevent degradation. For long-term storage, consider using desiccants or an inert atmosphere.
